To an whom it may concern: "Be it known that I, VmNoN Hons'ram, a citizen of the United States, residing 'at Minneapolis, in the county of Hennepm and State of Minnesota, have invented certain new and useful Improvements in Teeth for Excavating Shove1s,"0f which the following is a specification. I

My invention relates to teeth for excavating shovels and an object 1s to PIOVldB a y point, these two parts being so constructed tooth,

that the point ma ,be readily and securely attached to the ody member in reverse position. p

. The full objects and advantages of my invention will appear in connection w1th the detailed description thereof and the novel features of my inventive idea will be particularl pointed outin theclaims.

In e accompanying drawings, which illustrate the applicat1on of my invention- Fig. 1 is aside elevational view of the device attached to a .wall ofan excavating the shovel being shown partly broken awayand in section. 'Fig. 2 1s a to plan view. Fig. 3 is ,a vertical sectlona view.

Fig. 4 is a longitudinal sectional view of the point detached. Fig. 5 1s a s1de eleva- 1 tional view of the forward portion of the body member. Fig. 6 is a planview of the forward portion 0 the body member. F1g; 7 is a side elevational view of the rude opposite that shown in Fig. 5. 8 is a new forward lip or edge of the wall 16 of the I upper in section on the line 8- ig. 1.

As shown in the drawings a tooth comprises a body member 10 and a detachable reversible point 12: The member 10 on 1ts up r side is. provided with a rearwardly inc ined lug 14 and adapted to fit over the shovel and the upper surface of the member 10 is shaped to -fit the wall 16 to which it is securely fastened by r1vets 18. The body member 10 at its forward end 1s provided with a wedge-shaped nose 20 having and lower inclined surfaces, the lug 14 forming a'continuation of the upper surface. The two side surfaces of the body member are parallel and one of them is provided .with a half round tapered recess 22 and the other side is provi ed'with a rib 24 which provides a locking shoulder. The

12 1s wedge-shaped and is provided a body member and a tapered pin 32 is provided to 'the loft e point to be securely locked with the point 12 with a chamber 25 into which thenose 20 hts. The chamber 25, as will be apparent from Figs. 1, 2, 3 and 4, is open only at the rear of the point. The o1nt is stronger and 1s held more secure upon the nose than would be the case i thesigles of the point were open. The rib 24 is considered one recess being opposite to. that of the I other. The recesses 26 continue through the upper and lower surfaces of the amt to form round openings 28 and 30, e 0 en- -ing 30 being larger than the opening on 1 A account of the taper of the fit thetapered recesses 22 and 26 when these recesses register with each other.

The operation and advantages of vention will now .be obvious. The inc ned lug '14 aids in holding the body member 10 securely on thewall 16 of the shovel. When the point 12 is applied to the nose 20 of the body member the rear edge of the recess 26 on one side of the point slides past therib 24 and has a locking engagement with the shoulder on the rib, as will be a parent from Fig. 8. The recess 26 on the ot er side of the point comes into register with the recess 22 and the point is firmly secured by drivin the in 32 into these registered recesses.

in causes the recess on the other side rib When the oint 12 becomes worn on its'lower side t e pin 32 is removed,

1. A tooth of the class described comprising a body member having a wed -shaped nose, said nose having an open si ed recess formed in the exterior surface of one of its sides, a wedge-shaped oint containin a chamber into which said nose is ada t to fit, said point having an open side recess formed in the interior surface of one of its sides and complementary to said first mentioned recon, and a pm adapted to pass myi mso he orce exerted by driving in is detached and then re laced in -inclined recesses 26 on op osite nose; a we -shaped int contai e are registe with each other; chamber intowhich sai nose is adap tov o 2.
